Sel-Impact by Mickael Chatelain - Trick

This trick really fools the eye with just one card that can be shown front and back! It starts off as the Ace of Spades. Now, watch closely!

Very slowly, the Ace of Spades transforms before their eyes. It's morphing, live and close-up! The spectators' eyes can't explain what they're seeing! The Ace of Spades changed into the Ace of Clubs in full view! Was it real or just an illusion? As the card is slowly advanced towards the spectator, and during this brief trajectory, it reverts back from Clubs to Spades!
